Dichloromethane, methanol and aqueous extracts from the leaves of Terminalia triflora were investigated for their inhibitory effect on polymerase and ribonuclease activities of HIV reverse transcriptase.The most potent activity was found in the aqueous extract, which inhibited both polymerase and ribonuclease activities of the enzyme with an IC50 of 1.6 micro g/mL and 1.8 micro g/mL respectivel...

Serotonin plays important physiological functions at the intestinal level. However, nothing is known concerning its inactivation mechanisms in the human intestine. So, the aim of this work was to characterize the uptake of serotonin at the apical and basolateral membranes of human intestinal epithelial (Caco-2) cells. Uptake of [3H]serotonin at the apical membrane of Caco-2 cells was specific a...

Complex profile and micro-channel generation in silica glass with higher machining depth is an exigent issue to the researchers by μ-ECDM process. Fundamentals of come from hybrid amalgamation effects ECM EDM. The intensity sparking contributes material erosion melting chemical etching job-specimen. paper consists parametric influences as well comparative analysis on (MD) surface roughness (Ra)...

The carbohydrate derived nonionic gemini surfactants have been emerged as a result of our present day interest in environmentally compatible chemicals. Reverse micelles formed by surfactants can be used for selective solubilization and reactions which exploit their nanometer size, micro-environments and mimics the membranous biological system. Novel carbohydrate based non-ionic gemini surfactan...

with development of technology and science and continuous increase in productivity, product life cycles are shortened and customer demands are more personalized and diversified, which makes companies face with ever changing and unpredictable competitive environment. therefore, rapid response to market competition has become one of the main focuses and the competitive advantages. today, one of t...

the objective of the current study was to evaluate the reproducibility of a reverse transcriptase pcr (rt-pcr)-based technique to differentiate viable and dead salmonella cells in raw and sterilized milk. the microorganism was initially inoculated into the milk samples followed by incubating at 37°c for 4 h prior to inactivation by heat at 80°c for 10 min. the treated and non-treated samples we...

The Micro pump is an essential component in a Micro Total Analysis System (μTAS). A feasible and reliable design of the micro pump is a key for the development of the μTAS. The Valve-less Rectification Micro Pump (VRMP) has many advantages, such as: non-moving parts, independent of fluids and channels properties, reliable, and easy to fabricate. Fluid diodicity is an essential parameter of the ...

abstract:the general perception of islamic finance is that it prohibits the practice of paying and receiving interest, but islamicfinance is much broader than interest rate prohibition. islamic financial services can be viewed as a set of financialservices which are diversified based on the needs of society.since in the iranian economy most of the enterprises are micro and/or small, micro finan...
